introduction: herbal medicine and medical plants such as ziziphus vulgaris l. are widely used for treatment of diseases such as diabetes mellitus. in the present study, we have investigated effects of alcoholic extracts of z. vulgaris fruit on serum glucose, triglycerides, ldl, hdl and activities of aminotransferase enzymes in streptozocin (stz)- induced diabetic adult male rats. methods: herba...

The effect of chilling on translocation in higher plants was reviewed by separate consideration of path, sink, and source-cooling effects. The response of the sink to chilling indicates that the effect is mainly due to the inhibition of a metabolic process, while the response of the path to chilling suggests that the effect is mainly due to physical damage such as alteration of membranes. Sugar...

Thyme (Thymus vulgaris L.) is a commonly used flavoring agent and medicinal herb. Several chemotypes of thyme, based on essential oil compositions, have been established, including (1) linalool; (2) borneol; (3) geraniol; (4) sabinene hydrate; (5) thymol; (6) carvacrol, as well as a number of multiple-component chemotypes. In this work, two different T. vulgaris essential oils were obtained fro...

Use of non-glossy collards as a trap crop for control of the diamondback moth, Plutella xylostella (L.), in commercial fields of cabbage in New York was unsuccessful because it neither reduced the number of larvae on cabbage nor concentrated the insects on collards. In laboratory and outdoor screenhouse experiments, P. xylostella preferentially laid its eggs on the glossy-type Barbarea vulgaris...

Rates of photosynthesis, sucrose synthesis, starch accumulation and degradation were measured in sugar beet (Beta vulgaris L.) and bean (Phaseolus vulgaris L.) plants under a square-wave light regime and under a sinusoidal regime that simulated the natural daylight period. Photosynthesis rate increased in a measured manner in direct proportion to the increasing light level. In contrast to this ...

background and objectives: despite the vast production of new antibiotics in the last three decades, resistance to these drugs by microorganisms has increased and essential oils (eos) have been recognized to possess antimicrobial properties. methods:  in the present study, eos obtained from aerial parts of thymus vulgaris l., lavandula angustifolia mill., rosmarinus officinalis l. and mentha pi...

Two new cycloartane glycosides, named aquilegiosides K and L, have been isolated from the dried underground parts of Aquilegia vulgaris. Their structures were determined by two dimensional (2D) NMR spectroscopic analysis and chemical evidence.

The aim of this study was to screen 15 essential oils of selected plant species, viz. Lavandula angustifolia, Carum carvi, Pinus mungo var. pulmilio, Mentha piperita, Chamomilla recutita L., Pinus sylvestris, Satureia hortensis L., Origanum vulgare L., Pimpinella anisum, Rosmarinus officinalis L., Salvia officinalis L., Abietis albia etheroleum, Chamomilla recutita L. Rausch, Thymus vulgaris L....
